Sweden Application July 25, 1945, Serial No. 607,002

In Sweden April 24; 1943 My invention relates to baby carriages and the like which are provided with a body of stiff material as sheet metal, wood, fibre, basket work and such like. 7

The principal object of my invention is the provision of a baby carriage with a body of stiff material which can be folded together so that it in this state needs very little space and is easy to transport.

Another object of the invention is a foldable baby carriage which can be folded and unfolded in one simple operation only.

A further object of the invention is a foldable baby carriage, the parts of which will automatically lock each other in proper state at the end of the unfolding operation, e

Other objects and advantages of the invention relating to the particular arrangement and construction of the various parts will become apparcut as the description proceeds.

In the accompanying drawing:

Fig. 1 is a'longitudinal section view of the baby carriage in its extended state. I

Fig. 2 is an end view of the same with its parts folded together.

Fig. 3 is an enlarged fragmentary longitudinal section view of the one end portion of the baby carriage including modified sectional side walls.

Fig. 4 is a cross section of the arrangement shown in Fig. 3.

Fig. 5'is an enlarged'fragmentary longitudinal section view of the portion shown in Fig. 3 but in another embodiment. 4

Referring in detail to the different parts of the baby carriage 2 designates a bottom for the carriage with its padding 2, which bottom is fixed to a bottom frame I. A back 3 for the body is swingably connected to the foremost end-of the bottom frame I by means of pivots l2. The bottom frame is supported by support arms 4 turnably connectedto the bottom frame I as well as to a base frame 5 of the carriage, the base frame being carried on the carriage axles byintermediate springs. When the bottom is pushed rearwards the support arms will swing downwards and the bottom will be lowered. To hold the bottom in-raised position the back 3 is provided with catches B which in upright position of the back and of side walls! of the body will grip over cross directed side pins 13 in the side walls as shown in Fig. 1 and Fig. 8. When the back 3 is swung rearwards the catches will be disconnected and the bottom is free to be lowered.

Intheembodiment of Figs. 1 to 4 the side walls I of the body are mounted to the base frame 5 12 Claims. (Cl. 296-27) 2 by means of hinges 8 or such like, so that they can be folded inwardly, and the arrangement is I such that the bottom frame I in its normal raised position will prevent the side walls 1 to be folded towards each other as shown in Fig. 4. I

The side walls I are held in their normal upright position also therethrough that their lower portions situated beneath the hinge pivots will be hindered in the swinging movement by the raised normal push handle bow 9, which lower portions at the folding movement will swing outwardly and upwardly. The push handle bow is swingably mounted to the-base frame 5 and can from a horizontal position be swung upwardly and take up two alternative positions as shown in Fig. l by 9 and 9'. In this. position the handle cooperateswith catches l0, ID on the outer sides of the side walls and will at the same time press against side guides H on the side walls helping to make the locking of the side walls secure and rigid.

When the body of the baby carriage is tobe folded together the push handle 9 is swung down to horizontal position. Thereafter the back 3 is swung down releasing the catches B from the side pins l3. When now the back is drawn rearwards the bottom will follow and be lowered by a downward swinging movement of the support arms 4, and the side walls I will clap down over the back overlapping each other as seen in Fig. 2. As the bottom in its normal position locks the side walls in upright position, the folding of the side walls is in dependence of the lowering of the bottom. The arrangement of the different parts is such that the movements of the same can be to a certain degree carried through simultaneously; The unfolding; of the body. occurs in reverse order, and at the end of the unfolding operation the parts will be automatically locked together. v I

In the 'embodimen. of Fig. 5- the side walls are foldably mounted on the bottom frame l instead of on the base frame 5 with the result that the side walls will follow the lowering movement of the bottom. In upright position the side walls are held by the push handle and are themselves locking the bottom in its normal position by means of locking pins [5 extending from the side walls beside the support arms 3 as seen in Fig. 5. Thusthe lowering of the-bottom-is-in this case in dependence of the folding of the side walls as the side walls must be folded previous to the lowering of thebottom.

The side walls I can be divided along the horizontal hinge axle line 14 as shown in Figs. 3 and- 4, so that the upper portions only of the side walls will take part in the folding operation the lower portion 1' being fixed relative to the frame 5. The back can be arranged tohold theside walls in upright position. The carriage can be provided with two backs or gables and with one or more axles. If desired the back can be arranged to be swung down on the already folded side walls.

Although preferred embodiments of my invention have been illustrated it will be understood that modifications may be made within the spirit and scope of the appended claims,
